WHEEL FOR TRACTION-MACHINES.

SBEGIFICATION forming part of Letters Patent N0. 791,626, dated June 6, 1905.

Application filed October 17, 1904. Serial No. 228,885.

To (ZZZ whom it may concern:

Be it known that I, WILBUR S. KELLEY, a citizen of the United States of America, and a residentof Newton, Jasper county, Iowa, have invented a new and useful Wheel for Traction-Machines, of which the following is a specification.

The object of this invention is to provide an improved construction for traction-wheels whereby the wheel is prevented from slewing or moving laterally, has its traction properties increased, and may be employed when desired on a track-rail.

My invention consists particularly in the construction of a wheel-rim, as hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which Figure 1 is'a side elevation of a portion of a wheel embodying my improved construction. Fig. 2 is a rear elevation, partly in section,

of a wheel embodying my improved construction. Fig. 3 is a rear elevation of a portion of a wheel embodying my improved construction and mounted on a track-rail.

In the construction of the device as shown the numeral designates a wheel-rim, preferably formed of metal and relatively broad and thin. The wheel-rim 10 is constructed with a flange 11 on its inner margin and projecting peripherally therefrom. The wheelrim 10 may be connected by spokes 12 to a hub 13 of any desired construction, and said hub may be mounted on or have mounted therein an axle of any desired form. (Not shown.) A plurality of lugs 14 are formed on or fixed-to the tread-surface of the wheelrim 10, and said lugs may be arranged transversely of the wheel-rim, as shown, or in any conventional or desired manner. A trackface or tread-face 15 is provided on the wheelrim 10, between the inner ends of the innermost row of lugs 14 and the flange 11, which tread-face is of a width at least as great as that of the tread-surface of a track-rail 16, as shown in Fig. 3.

Wheels constructed as illustrated in Figs. 1, 2, and 3 may be employed to support traction-engines or other traction-machines and employ the power of such engine or machine in advancing the same over the surface of the soil, the traction-lugs 14 increasing the frictional engagement between the wheel-rim 10 and the surface of the soil, or the traction-engine or other traction-machine may be mounted with its wheels supported on track-rails 16, the tread-faces 15 of pairs of wheels being gaged or spaced apart coincident with the .gage of the track on which the machine is to be driven. In either instance, whether on the soil or on a track, the traction-wheels may be employed to advance the machine by which they are carried, in the one place engaging the soil through the medium of the lugs 14 and in the other place engaging the trackrails through the medium of the tread-spaces 15, provided between the innermostrows of lugs and the adjacent flanges 11.

When the wheel is employed to advance the machine on the ground, the flange 15 engages and cuts into the soil and limits and prevents slewing or lateral movement of the wheel, and when said wheel is employed on a trackrail the flange serves to limit lateral movement of the wheel relative to the rail and maintains the desired relation between them.

I claim as my invention 1. A traction-wheel, having a rim, said rim formed with a peripheral flange on one margin, lugs rigidly mounted on and transversely of the face of said rim, said lugs spaced apart from said flange to form an annular treadface on said rim adjacent said flange.

2. A traction-wheel, having a rim, said rim- Signed by me at Newton, Iowa, this 16th day of March, 1904.
